The warmth loving plant hadn't been known in the alpine and prealpine phytogeographical region of Slovenia until recently. In 2008 it was discovered on an isolated, locally sunny and warm place in Trenta valley at the mouth of Lepena side valley. It is now showing its beautiful violet flowers year after year on more or less the same place. For now this is its only known location in Julian Alps and among the most northern in Slovenia.Ref.:(1) Personal communication with Dr. Igor Dakskobler, Natural History Institute Jovan Hadi, SAZU.(2) M.A. Fischer, W.
